CVE-2026-105643

Published Oct 5, 2026·Updated Oct 7, 2026

NVD Description

Ghost is a Node.js content management system. From version 6.34.0 until 6.67.0, embed cards in the Ghost editor could bypass protections against stored cross-site scripting. Any staff user, including Contributors, could store scripts in post content that ran when another staff user opened the post in the editor, potentially compromising that user’s admin session. Self-hosted sites should leave the new  security.embedPreviewUrl  configuration option at its default value. This issue is fixed in version 6.67.0.
